BIG RIFF is a new work by John Frith for 8-part trombone ensemble. It was written as the opening "Anthem" for "Trombonanza 2017", which is a festival takes place annually in the town of Santa Fe, Argentina. Mr. Frith was commissioned to compose this workto open the festival. The music is about 5 minutes in length and features strong Latin rhythms throughout. The work builds and builds as it adds layers of complexities including a jazz solo for one of the players. The all the middle parts are playable byintermediate performers. Part 1 can be performed on alto or tenor and goes up to high "F's". Part 8 is quite low. The work ends in a big climax after building up throughout. Very fun work to perform with a massed group. -the publisher
